Earlier this year, I introduced 4 new chicks to my flock bringing the total to 10. One of the chicks escaped the first week. Once they were old enough I incorporated them all together in the same run. I almost immediately saw the number of eggs drop from 5-6 a day to 4 consistently. Then one of my hens became broody and I noticed another drop to 3 a day. Also one of the older hens died during this time. I was able to break her from being broody but the egg production has continued to go down. Recently I am getting only 1-2 eggs a day from 8 hens. This has been a continuous decline for the past 4-5 months at least. They all look and act healthy except for low egg count. Is there anything I can do?
